Colour shift car paint / Chameleon car paint
You can try something like this. Reflection works (as a coordinate) on it's own, but I feel it looks better when the vectors are combined with the Window vectors.

The &quot;glitter&quot; effect, you can get by using a White Noise texture as the metallic factor. I added the Voronai Texture, because it's a trick to make it so the White Noise isn't &quot;infinitely zoomable&quot;. It also allows you to change the randomness of the shapes. I added the MixRGB to mix it with white to bring the whole texture back closer to &quot;pure metallic&quot; (100% white).
